The church of San Ginés is one of the oldest churches in Madrid. It was one of the churches of the medieval Madrid, of Mozarab origin, from between the 12th and 13th centuries, and its name comes from the fact that it was dedicated to the patron saint of notaries and secretaries, Saint Genesius of Arles (San Ginés de Arlés). it was rebuilt in 1645.
The church is preceded by an atrium enclosed by railings. It has a Latin cross plan, with a nave and two aisles separated by semicircular arches and several side chapels and the altarpieces belong to the Neoclassical-Romantic school. It was, however, totally reconstructed after suffering several fires, so few remnants of the original church, such as the bell-tower, remain. In 1870, the loggia and atrium facing the Calle Arenal were added.
One of the most curious items on display is a stuffed crocodile, which is said to have been brought over from the Americas during the reign of the Catholic Monarchs.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
